Title: Slat of rolling shutter for building and production thereof
Inventor: YOSHIDA KAZUAKI
IPC: E06B9/17
Filed: 1993-10-22
Abstract: PURPOSE:To reduce noises, by forming an uneven part at least at one of mutually contacting faces of the connection part, when jointing a plurality of slats to form a chain connection by an interlocking joint so as to unify them. CONSTITUTION:A plurality or recessed groves 9 are formed at every appropriate interval at the inner peripheral face of the outside interlocking connection part 8 where the inside interlocking connection part 7 contacts in the inside or outside interlocking connection parts 7, 8 of slats 6. The contact part between the connection parts 7, 8 is separated by the groove 9. The friction of the connection parts 7, 8 is reduced at the time of winding up and off. When the connection parts 7, 8 are molded by a roll, the eccentric form of the connection parts 7, 8 can be avoided by the grooves 9 and the shutter curtain does not slide on the guide rail. In this way, noises are reduced and a calm condition can be obtained.

Title: Image forming device
Inventor: OKADA NORIKAZU
IPC: B41J29/46
Filed: 1997-10-03
Abstract: PROBLEM TO BE SOLVED: To quickly detect the operative state of a device body and the occurrence of an abnormal state, without causing any trouble for the surroundings, even if an operator is far from the device body. SOLUTION: When a control part 34 receives a detection signal as a jam in a copying machine body 10 is detected by a sensor 29, the control part 34 makes an alarm operate by a voice outputting part 28, to display a message that the jam occurs to a display part 18. Simultaneously with this, the detection signal is transmitted to a remote copying state transmission machine 12 through a signal transmission and reception part 26. A control part 46 of the remote copying state transmission machine 12 generates vibration by a vibration generating part 42, based on the detection signal received by a signal transmission and reception part 40. Thus, even if an operator is far from the copying machine body 10, the operative state can be detected in a real time, without causing any trouble for the surroundings.

Title: Rolled material inspecting device
Inventor: GOTO MASATO
IPC: G01B21/20
Filed: 1987-11-17
Abstract: PURPOSE:To accurately detect a sampling point with high accuracy by synchronizing constant-interval point tracking by measuring a phase difference by a phase difference measuring means and correcting it by a sampling point correcting means. CONSTITUTION:The phase difference measuring means 14 measures the phase difference of the output signal of a sampling distance arithmetic means 11 (or 12) for rolling (or for measuring). The sampling correcting means 15 corrects a deviation in sampling between the means 11 and 12 according to the phase difference measured by the means 14. Then the sampling from the means 12 is matched with the sampling from the means 11 with the output signal of the means 15. Therefore, no deviation in sampling is generated at the time of switching from constant-interval point tracking by a rolling roller to constant- interval point tracking by a measuring roll and the sampling is accurately detected with high accuracy.

Title: Thread catch wiper of front sweep type
Inventor: SUZUKI ICHIRO
IPC: D05B65/06
Filed: 1990-10-27
Abstract: PURPOSE:To have certain sweep of a thread and prevent interference with other works by allowing a mounting table to collide with the tapered surface of a pin to cause it to run away in the pin axial direction when a wiper arm is going to return after rotation backward. CONSTITUTION:When a wiper arm 2 rotates ahead together with a mounting table 4 after thread cutting, the tapered part 4a of the mounting table 4 acts on a pin 3' of an arm 3a to depress the mounting table 4, which causes depression of a thread support wiper 7. Accordingly a gap is generated between the hook of a hook-equipped wiper 6 and a recess in the thread support wiper 7, and a needle thread is taken in this gap. When rotation of the mounting table 4 further advances, the action of the tapered part 4a on the pin 3' is disengaged, and the hook-equipped wiper 6 is restituted together with the mounting table 4 to nip the needle thread. When the wiper arm 2 returns upon rotating backward, the mounting table 4 collides with the tapered surface on the pin 3' to cause it to run away in its axial direction, so that the nipped needle thread will never be liberated.
